Abrupt decline of microplankton species richness linked to coastal inflow in an Arctic fjord

Limnology and Oceanography, Volume 70, Issue 9, Page 2688-2702, September 2025.
Abstract Species richness can be important for the functioning and resilience of marine ecosystems, with planktonic protists forming the base of the marine food web. Climate change‐driven shifts in water mass distributions are projected to alter plankton diversity.

Effect of food composition on egg production and hatching success rate of two copepod species (Calanoides carinatus and Rhincalanus nasutus) in the Benguela upwelling system [PDF]

, 2005
We have analysed the daily egg production (EPR) and hatching success rates of the calanoid copepods Calanoides carinatus and Rhincalanus nasutus as a function of nano- and microplankton concentration and composition in the northern Benguela upwelling ...

Impact of copper and iron on growth and silicic acid uptake in two Southern Ocean diatoms

Limnology and Oceanography, Volume 70, Issue 6, Page 1606-1620, June 2025.
Abstract Copper (Cu) and iron (Fe) are vital micronutrients that influence diatom physiology, growth rate, and nutrient stoichiometry. This study examines the interactive effects of Cu and Fe on two Southern Ocean diatoms, Proboscia inermis and Chaetoceros flexuosus, cultured under varying Fe and Cu conditions.

Remediation of Pb(II) and Cd(II) in Sea Water by Skeletonema costatum

Sustinere: Journal of Environment and Sustainability, 2017
The heavy metals that polluted sea water can end up polluting fish pond too. Hence, it is necessary to remove the heavy metals before sea water enters the fish pond.

Paramoeba atlantica as a Natural Intracellular Niche for Vibrios in Marine Ecosystems

Environmental Microbiology, Volume 27, Issue 6, June 2025.
Various vibrios can colonise a large vacuole called VCV (Vibrio‐containing‐vacuole) within Paramoeba atlantica. The VCVs acidify and the vibrios multiply and remain alive inside the VCVs for hours. The vibrio found associated with Paramoeba atlantica can be pathogenic to oysters, suggesting that Paramoebidae are a potential reservoir for pathogens ...

More Than a Stick in the Mud: Eelgrass Leaf and Root Bacterial Communities Are Distinct From Those on Physical Mimics

Environmental Microbiology Reports, Volume 17, Issue 3, June 2025.
Unique communities inhabit eelgrass leaves and roots compared to physical mimics and their environment. We examine which taxa vary to determine what host–microbe relationships may be mediate by biotic interactions. This indicates that eelgrass leaves and roots may just unique environments for microbes, but also could indicate more active partnership ...
